While searching for new multicomponent quasicrystalline alloys, the authors have suggested a principle of composition activity in the quasicrystal constitution. This means that some new quasicrystals can be constituted by adding several quasicrystalline alloy compositions, and these alloys can be obtained by means of rapid solidification or ingot processing. Guided by this principle, Al-Mn-Cr, Al-Cu-Fe-Mn, Al-Cu-Fe-Cr, Al-Cu-Fe-Cr-Mn, Al-Mn-Ni-Ti, Al-Mn-Fe-Ti, Al-Cu-Fe-Ni-Ti and other multicomponent quasicrystalline alloys have been found. A recent study used Al[sub 70]Pd[sub 20]Mn[sub 10], Al[sub 65]Cu[sub 20]Fe[sub 15] and Al[sub 85]Cr[sub 15] quasicrystalline alloys to formulate new alloys. Both Al-Cu-Fe-Pd-Mn and Al-Cr-Pd-Mn alloys are quasicrystalline. In this paper, they discuss these two quasicrystals, their formation, electronic diffraction and composition scope and thermal stability in detail.
